tic
clc; close all; clear all;  
delete(instrfindall);
s = serial ( 'COM5', 'BaudRate', 115200);
set(s, 'Timeout',60);
s.InputBufferSize =37020;
tic
fopen(s);
%for i=1:20
data=fread(s);
----------------------------------------------------------
s = daq.createSession('ni');
s.addAnalogInputChannel('cDAQ2Mod1', 0, 'Voltage');
s.addAnalogInputChannel('cDAQ2Mod1', 1, 'Voltage');
s.Rate = 2000
s.DurationInSeconds = 60;
[data5,time] = s.startForeground;
toc

I see no parfor or switch or matlabpool in your code?

You might be able to use spmd with two labs, one for the data acquisition and the other for the serial fread(). I do not have enough knowledge of the Parallel Computing Toolbox to be sure that it can be done.
